Claims. (01. 28--70) The invention relates to thread cleaners, such may be employed. The holes 11 and 12 make it as are used on textile machines of various types, possible to attach thread guides, such for examfor removing and detecting fluff, lint, slubs, knots, ple as shown at 15 and 16, either at the top or foreign matter, enlargement or other imperfecbottom of the bracket, or at both the top and bot- 5 tions from or on threads or other filaments. tom, as may be found most suitable for the work It has for one of its main objects to provide a to be performed. device on which the blades between which the A channel-shaped socket 17, having overlapcleaning is performed may be readily and speedily ping flanges 18 and an upwardly extending bearremoved and inserted without the use of any tools, ing 19, is pivoted on the support 13 by means of 10 or the adjustment of any screws or other adjusta bolt 20 and nut 21.

By riveting the blades on a separate plate, as here shown, instead of merely milling or sawing the slot 39 in the blades, it is possible to grind the sides of the slot and thus assure greater accuracy and less wear on the thread. By locating the spring means between the socket and the support 13, as shown in Fig. 1, there is no danger of their being clogged with floss or dirt.

Having described my invention and its advantages, What I claim as new and wish to protect by Letters Patent is:

l. A thread cleaner of the class described comprising, a bracket having means for attaching it to the machine on which it is to be employed and means for attaching one or more thread guides, a support formed on said bracket, a socket pivoted on said support, a plate having a pair of threadcleaning plates secured on its front end, the rear end of said plate insertable in said socket, selfacting spring means for clamping said plate in said socket, said spring means consisting of a wire spring the free ends of which engage in notches cut in the sides or" said plate, means associated with the socket for preventing movement of the blades in a direction from or toward which a thread is traveling through the device, and means associated with the plate to prevent its improper insertion in the socket.

2. A thread cleaner of the class described comprising, a bracket having means for attaching it to the machine on which it is to be employed and means for attaching one or more thread guides, a support formed on said bracket, a socket pivoted on said support, a plate having a pair of thread-cleaning plates secured on its front end, the rear end of said plate insertable in said socket, self-acting spring means for clamping said plate in said socket, said spring means consisting of a flat spring secured in said socket and having a transverse ridge engaging in a transverse groove formed in said plate, and

means associated with the socket for preventing movement of the blades in the direction from or toward which a thread is traveling through the device.

3. A thread cleaner of the class described com prising, a bracket having means for attaching it to the machine on which it is to be employed and means for attaching one or more thread guides, a support formed on said bracket, a socket pivoted on said support, a plate having a pair of spaced thread-cleaning blades secured on its front end, the rear end of said plate insertable in said socket, and self-acting spring means for clamping said plate in said socket, said spring means consisting of a fiat spring secured in said socket and having a transverse ridge engaging in a trans- Verse groove formed in said plate.

4. A thread cleaner of the class described comprising, a bracket having means for attaching it to the machine on which it is to be employed and means for attaching one or more thread guides, a support formed on said bracket, a socket secured on said support, a plate having a pair of spaced thread-cleaning blades secured on its front end, the rear end of said plate insertable in said sock et, and self-acting spring means for clamping the plate in the socket formed integrally with the socket, said spring means consisting of flat springs having transverse ridges engaging in transverse grooves formed in said plate.

5. A thread cleaner of the class described, comprising, a bracket having means for attaching it to the machine on which it is tobe employed and means for attaching one or more thread guides, a support formed on said bracket, a socket swingingly mounted on said support, a plate having a pair of thread-cleaning blades secured on its front end, the rear end of said plate insertable in said socket, the socket made channel-shaped with the edges of the channel bent inwardly towards each other to prevent movement of the thread-cleaning blades in the direction from or towards which the thread is travelling through the device, and self-acting spring means for clamping said plate in said socket.
